Jcadwell - just a note to you when looking for precision shaft - try Reid Tool Supply Co. (reidtool.com). I just bought the same 3/4" 48" shaft for $32. and change. Reid beat McMaster, MSC and Enco for Thomson 60 case harsened shaft. I also got the pacific plain frelon lined bearings for about the same as all the others. I might be a little leary of the nylon plain bearings due to tolerancing and potential thermal expansion. But if they fit and are close enough for you, they sound like a great bargain.
